“True love is first, love which does not conceal, and it does not conceal in two senses. First, it does not conceal because it has nothing to hide. It has nothing shameful which has to be hidden. It does not shun the light. It is willing, and is such that it is always willing to show itself in front of witnesses. It is also a love which does not conceal its aims. True love does not hide the true objective that it seeks to obtain from the one it loves. it is without subterfuge and does not employ roundabout means with its partner. It does not keep itself out of sight of witnesses, or of its partner. True love is love without disguise. Second, true love is an unalloyed love, that is to say, without mixture of pleasure and displeasure. It is also a love in which sensual pleasure and the friendship of souls do not intermingle. To that extend it is therefore a pure love because unalloyed. Third, true love (alethes eros) is love which is in line with what is right, what is correct. It is a direct (euthus) love. It has nothing contrary to the rule or custom. And finally, true love is love which is never subject to change or becoming. It is an incorruptible love which remains always the same.”
